SPECIFICATION forming part of Letters Patent No. 730,303, dated June 9,1903.

Application filed October 1, 1902 .T0 at whom it may concern:

, Be it known that I, ALONZO D. SEAMAN, a citizen of the United States,residing at Mih' waukee, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements inGolf-Balls, of which the following is a specification, reference beinghad to the accompanying drawings, forming a part thereof.

The main objects of this invention are to provide a golf-ball with anelastic body that will not become detached from the inclosing shellor'cover and lose its resilience if some of its elastic sections aresevered, and generally to improve the construction and quality of ballsofthis kind.

It consists in certain novel features of construction and in thearrangement and combinations of parts hereinafter described in detail,and particularly defined in the claims.

In the accompanying drawings like letters designate the same parts vinthe several figures.

Figure 1 is a medial section of a ball constructed according to myinvention. Fig. 2 is a projection of the elastic body or outercore-section of the ball, the outer shell or cover being removed. Fig. 3is a projection of the central or inner core'section, and Fig. 4 is aperspective View of one of the elastic rings of which the outercore-section is composed.

My improved ball is composed of a central or inner core-section a, anelastic body or outer core-section b, and a shell or cover 0. Thecentral or inner core-section a is preferably made of some hard orcomparativelyinelastic material, such as gutta-percha, and is preferablymolded or shaped to approximately spherical form.

The elastic body I) is composed of separate elastic rings (1, stretchedover and arranged Serial No. 125,471. (No model.)

section and to bind and hold each other in place. These rings, which areprimarily and normally of smaller diameter than the inner core-sectiona, as shown by Figs. 3 and 4, may be conveniently made by cutting rubbertubing of the proper thickness and diameter into short lengths. When theelastic body I) has been thus built up to the desired size and shape, itis incased in a shell or cover 0, of gutta-percha or other tough, hard,or com paratively inelastic material, which will adhere to the elasticmaterial of the body and give the ball the desired rigidity 0r firmness.

A ball thus constructed will keep its shape and retain its elasticityand resiliency for a long time. If some of the separate elastic rings ofwhich the outer section of the body is composed are severed, theremaining rings will not be affected thereby and will help to hold themin place, thereby preventing the core or body from becoming detachedfrom the inclosing shell or cover and preserving the elasticity andresiliency of the ball.

By encircling the core with narrow rubber rings instead of with broadthin rubber bands at substantially uniform tension in cross-section, orfromedge to edge of the ring, is obtained instead of an inequality oftension arising from a greater tension at the center than at the edgesof a broad thin band, occasioned by such a band conforming to thespherical shape of the core. Furthermore, the narrow rubber rings beingstretched under a high tension around the hard core form a comparativelythin but yet stable and resilient cushion between the hard core orcenter and the hard shell, thus making the ball very responsive to ahard knock, while it at the same time supports the outer shell andreduces the liability of a permanent flattening tension over said coreand over each other, and a cover of gutta-percha, substantially asdescribed.

2. A ball consisting of a relatively inelastic spherical core, separatenarrow rings of elastic material to obtain substantially uniform tensionin cross-section when encircling the core and stretched under hightension over said core and crossing each other at different points andangles, and an inclosing shell of compara- :o tively hard inelasticmaterial, substantially as described.

In witness whereof I hereto affix my signature in presence of twowitnesses.
